Verified step by step guidance

Begin by understanding the concept of germ layers. Germ layers are the primary layers of cells formed during early embryonic development. These layers are the ectoderm, mesoderm, and endoderm.

Next, explore the process of gastrulation. Gastrulation is the phase in embryonic development where the germ layers are formed. It sets the stage for organogenesis but does not involve the differentiation into organs and organ systems.

Consider the process of neurulation. Neurulation is the development of the nervous system from the ectoderm, which occurs after gastrulation. It is a specific part of organogenesis but not the complete process of forming all organs.

Focus on organogenesis. Organogenesis is the process where the germ layers differentiate into organs and organ systems. This is the stage where the cells from the germ layers develop into the various organs of the body.

Understand the role of fertilization. Fertilization is the union of sperm and egg to form a zygote, which precedes the formation of germ layers and organogenesis. It is not directly involved in the differentiation into organs and organ systems.
